ELECTRIC BATEERY.

* To all whom c't may concern.'

tBe it known that I, DAvm H. WILSON, a citizen ofthe llnited States, residing at New York, in the county of New Yorlr and State ot New York, have invented a certain new and useful Improvement in Electric Batteries, of which the following is a specica` tion.

rllhis invention relates to electric batteries, and has for its object to provide a new and improved battery of this description. This invention has among other objects to produce a gravity battery which shall have a long lite and great reliability and cleanliness, with economy iii the consumption of zinc, and which cannot be short-circuited by the dropping of the zinc, and by means et which a large current may be produced. lhe invention is illustrated in the accompanying drawings, wherein,

Figure l is a' view showing one forni of battery embodying the invention,

Fig. 2 is a sectional view taken on line 2 2 of Fig. l.

llig. 3 is a sectional view taken on line 8--3 ot Fig. 2.

Lilie numerals referto like parts throughout the several figures.

' placed the electro .dll

its illustrated in the drawing, l have' shown a suitable jar l,v in which the battory solution, is laced. ln this jar are es 2 and 3. Electrode 2 is a co per electrode and is bent so that it can be ocated at any required distance tronithe bottom of the gar. rlhe electrode 2 is immersed in a solution of sulfate of co er. The electrode 3 is contained in a sha ow porous cup e, This zinc electrode is provided with a series of slots 15 which entend through the material thereof, pref erably trom a point near the center tothe outer rim lo. lhese slots permit the gases which are termed between the bottom of the zinc electrode and the inner tace of the cup el, to escape.

@n the Itop of this zinc A electrode is placed a layer l5, of felt or other suitable material, and 'on top of this felt is placed a guantity of insulating vbattery wasV t, which lls in the porous Acup and holds it rigidly in place in its proper relation to the f zinc'electrode. The tubing 7,V projects up thiou h thewax so as toallow the escape of gas w ich will form Ainside the Vporous'cup, and which passes up into the slots 15.- The rini i6 is preferably beveled on the under- Specieation @Letters Patent.

side lto allow the bubbles of gas to fall O and come to the surface.

The shank 8, of the zinc electrode is pro.

vided with a tube 9, to protectit from the action of the battery solution. The vbattery with said cover. As herein shown, the cover is provided with a collar l1, having a s'et screw 12 whichV projects therethrough and engages the shanh 8.

lt will be seen that by loosening this set screw the zinc electrode may be moved toward or away from the copper electrode, so as to vary thev amperage of the battery. This construction with the porous cup permits the broad surface of the zinc electrode to be brought much nearer the broad surface of the copper electrode when a large amperage is desired than could otherwise be done.

The conductor 13 is connected with the copper electrode and is provided with a suitable terminal for connecting it in the circuit. The zinc electrode is also provided with a suitable terminal 14, for connecting1 it in the circuit.

By bending the copper electrode as de- "raised a considerable distance from the bottom of the jar thereby permitting the electrodes to be brought a proper distance apart even when jars of various depths are used.

The porous cup moves with the zinc electrode and hence it prevents the two elec trodes from beingy short-circuited in the event the zinc electrode drops upon the copper electrode, or in the event the electrodes are brought too close together.

l. An electric battery comprising a gar, a copper electrode having bent portions by means oi which it issup ortedat a distance above the bottom of the Jar, a porous cup in said jar, and a zinc electrode in said porous cup, the porous cup supported by the zinc electrode.'
